SPECIFICATION forming* part ofl'IAetters` Patent No. 284,545, dated.September 4, 1888.

` i Application filed February 21, 1883. (Model.)

To aZZwhom z't/.may concern:

Beit `known that .I, GEORGE W. FAIR, of

'Daytom in thecounty of Montgomery and State of Ohio, have inventedcertain yneWand useful Improvements.,` in Heating-Furnaces and I dohereby declare that the following is a full, clear, and `exactdescription of the invention, Which Will enable others skilled in theart to `which -it appertains to make and use the naces, and it consistsin the improved construction, combination, and arrangement of parts ofthe same, as Will hereinafter be more fully described, and particularlypointed` out in the claims.

In the accompanying drawings, the letterA indicates the radiator, B thenre-place, and C the ash-pit. On each side of the ash-pit is an opening,D, closed `by a hinged door, E E. Through these openings the draftenters thefurnace, and may be regulated by openingor closing the doors Emore `or less. The draft en tering through these doors is ledthrough the`side grate-bars, F F, into the lire. These side grate-bars are providedwith a series of openings, G, through their Whole length and stand atright angles to the bottom grate, II, which may be of any desirableconstruction, and is `operated by a bar, I, passing through a slot inthe front plate of the furnace. f The air passing into there from thesides as Well as from the bottom through the Whole length of thefrecauses aperfect and even combustion in the Whole length ofthefire-place. ,l Y.

Above the door B', through which the fuel is fed and which opens intothe4 fireplace from the front, is an opening, J, covered by a circularadjustable register-plate,K, of the usual construction, leading intoaT-shaped tube orfunnel, L, Which opens intol two channels, Z,

one upon each side ofthe neck M, formed by the contractingl, sidesandtopR of the fireplace, which Achannelshave openings m on their innersides leading into the said neck, and conductingthe air passing throughthe ,tube L into contact with the\ascending produc-ts of the combustionin the re-place,where it is mixed with the same "and ignited, assist ingin consuming the smoke and causing an intense heat in the radiator. Byopening the register-plate Wider and admitting a larger amount of air,the combustion in the re-place 6o may be decreased, so that theregister-opening mayalso serve as a regulator for the combustion, andbybeing contracted in the said opening, immediately above the centerofthe fire, the smoke is partially consumed, and the hot air and'otherproducts of combustion ascending into the radiator are superheated.

The radiator A is cylindrical in shape, and a drum, N, open at bothends, passes longitudinally through it from the front to the rear 7o ina slightly-upward direction, admitting .of a

portion of the air to be heated passing through it. Y Inside theradiator, to the rear of opening M, extend a series of semi-annularpartitions alternatelyl from the bottom and the top of the 7 5 radiator,and extend slightly beyond the central plane of the same, serving toguide the `products of the combustion in an undulatory4 course throughthe radiator, subjecting all points of the same to the heat and,retaining 8o the latter in the radiator before passing out in thechimney through the aperture S.

The Whole furnace is inclosed` in a brick-` chamber, P, having openingsto admit the air to enter, and `to conduct it, after it has been heatedby contact with the radiator, through appropriate ducts to the roomsdesired to be heated. l

A chute or box, Q, leading obliquely from the side of the brick chamberinto the re- 9o place serves to conduct the fuel, and may be l filled,allowing the fuel gradually to slide down as it is consumed in the re.

nately extending from top and bottom, and ex- Ico tending beyond thecentralhorizontal plane of the radiator, substantially as set forth.

` consisting of the nre-place B, having arched sides and top R,contracting to form neck M, and having fuel-chute Q, grate H, sidegratebars, F, having transverse perforations G, and air-ducts D,perforated channels Z, radiator A, 15 drunl N, and semi-annularpartitions O, all constructed and combined to operate as and for thepurpose shown and set forth.

Intestiniony that I claim the foregoing as my4 own I have hereuntoaffixed my signature in 2o presence of two Witnesses.
